Download Supersymmetry Searches at the Tevatron in Run I and Run II. Book in PDF, ePub and Kindle
The authors review the searches for supersymmetric particles achieved by the CDF and D0 collaborations at the p{bar p} Tevatron collider at FNAL, at (square root)s = 1.8 TeV and with a total integrated luminosity of 110 pb−1, per experiment. The prospects for the forthcoming run at (square root)s = 2 TeV and an integrated luminosity reaching ultimately at least 20 fb−1, are also discussed.

We review current experimental results of searches for Supersymmetry (SUSY) at the Fermilab Tevatron Collider using the Run I data collected during 1992-1996. New results from the CDF detector in the jets + missing E{sub t} and lepton-photon channels are presented. Recent results from model independent searches at D0 using the SLEUTH algorithm are reviewed. We discuss the prospects for supersymmetry searches at Run II of the Tevatron, scheduled to start in March, 2001.

We review some of the latest results on Supersymmetry searches at the Fermilab tevatron Collider. The final states for supersymmetric processes are preferably described in terms of the physical signatures produced by the particles involved. Accordingly we look at: missing transverse energy, E{sub T}, related to the presence of neutral and stable supersymmetric particles; jets, from the decay of squarks or gluinos; leptons, coming for instance from gaugino decays; photons, predicted in gauge-mediated models. We discuss here some of the most recent results on SUSY searches performed at the Fermilab Tevatron by the CDF and D0 collaborations. The CDF and D0 detectors[1, 2] collected, during the 1992-96 period (Run I), about 100 pb−1 of p{bar p} collisions. The most relevant up-grades for the current run (Run II, started in March 2001) refer mainly to the tracking and trigger system, with minor improvements to the calorimetry and muon systems.

We discuss is the search for supersymmetry at the Fermilab Tevatron by the D0 and CDF collaborations in p{anti p} collisions at (square root)s = 1.8 TeV. The searches are performed in the jets plus E{sub T}, leptons plus E{sub T}, and photons plus E{sub T} channels. In these channels there is no excess of events over the expected backgrounds.

Both Tevatron experiments, D0 and CDF, have searched for signs of Supersymmetry in the present Run II data sample, using integrated luminosities of up to 260 pb{sup -1} collected in p{bar p} collisions at a center-of-mass energy of 1.96 TeV. In these proceedings, new results are presented in the search for squarks and gluinos in the jets and missing transverse energy final state, associated production of charginos and neutralinos with multilepton final states, search for the rare decay B{sub s} {yields} {mu}{mu}, searches allowing R-parity violation (muons+jets, multileptons), and searches in the gauge mediated supersymmetry breaking framework with the final state of two photons and missing transverse energy. In the absence of any significant deviation from Standard Model expectations, limits on the presence of new physics are set, which in many cases are the most stringent to date.

The results for searches for Supersymmetry at the Tevatron Collider are summarized in this paper. They focus here on searches for chargino/neutralino and the lightest stop, as well as scenarios with R-parity violation and split supersymmetry. No significant excesses with respect to the Standard Model were observed and constraints are set on the SUSY parameter space.

With almost 0.5 fb{sup -1} of p{bar p}-collisions delivered in Tevatron Run II, both experiments CDF and D0 are reporting first results from a vast number of search analyses. This article summarizes the current status of Tevatron searches for Higgs bosons within the Standard Model and its extensions as well as direct searches for supersymmetric particles. Signatures for production of squarks, gluinos, charginos and neutralinos as predicted by gravity- and gauge-mediated SUSY breaking scenarios have been considered. No evidence for Higgs bosons or SUSY particles has been found so far. New limits are derived which significantly improve on existing limits.

Download Search for Supersymmetry at the Tevatron Using the Trilepton Signature Book in PDF, ePub and Kindle
This dissertation describes a search for the associated production of the supersymmetric particles, the chargino and the neutralino, through their R-parity conserving decays to three leptons and missing energy. This search is carried out using the data collected at the CDF experiment at the Tevatron's = 1.96 TeV p-anti-p collider at Fermilab. The results are obtained by combining five independent channels with varying signal to background ratio. Overall, a total of 6.4 [plus minus] 1.1 background events from standard model processes and 11.4 [plus minus] 1.1 signal events for a particular choice of mSUGRA model parameters are expected. The observation of 7 events in data is consistent with the standard model background expectation, and the mSUGRA model is constrained. Limits are set on the cross section of Chargino-Neutralino pair production, and a limit on the mass of the chargino is extracted. A method of obtaining model-independent results is also discussed.
